Strap for Cosmograph Daytona White Gold / Black - Steel / Oyster

The lug width of the Rolex Daytona 126509-0001 is 20 mm. This measurement should be taken with a digital calliper at the inner distance between the lugs, flush against the case. It applies to all aftermarket straps compatible with this reference.

For the Daytona 126509-0001 in white gold, the most suitable straps are alligator Hornback or shell cordovan, whose natural grain and lustre complement the polished surfaces of the case. A vegetable-tanned calf leather strap is also an excellent choice, as it develops a patina over time that pairs well with white gold. For sporting contexts, vulcanised rubber with a white gold deployant clasp maintains metallic coherence.

The Daytona 126509-0001 features drilled lugs, allowing strap replacement using a fine-tipped spring bar tool (0.9 mm). It is advisable to work on a watch cushion and proceed carefully to avoid scratching the polished white gold surfaces. If in doubt, consult a watchmaker or the Casati Milano atelier for a safe strap change.
